V STORM-WATER INLET.

Application filed April '2,

This invention relates to improvements in storm water inlets. 7

It is the object of this invention to provide a novel and improved form of storm water oinlet adapted for manufacturing methods in production quantities, the device having'a substantially universal application to fit' varying conditions of installation and thereby being adaptedto eliminate to a large degree, the hand labor heretofore required in such installations. In the drawings:

Figure 1 is an axial section of a device embodying this invention.

Figure 2 is a plan view thereof. Like parts are identified by the same reference characters throughout the several views.

"In accordance with this invention the inlet is made in the form of a basin which may be cast of iron or other metal in the shape i ndi cated at 5. It is important to note that the basin is so designed as to have a considerable water capacity without any. abrupt curves,

recesses or sharp angles in which sandor other foreign matter may lodge. The necessity of-cleaning individual storm water inlets is thereby eliminated and the cast construction also eliminates the hand work here tofore necessary inbuilding inlets ofvma Thebasin shaped receptacle 5 provided with a broad flange at 6 upon which two courses of brick may be laid at 7 assh1mm1ng for the standard storm inlet frameSand slide enlet box 9. These parts correspond to general practice and are not necessary tothis invention in the identical form in which they kind have heretofore been built of brick and.

g elbow fitting. disrupt connections to the drain. This difficulty is eliminated in the present device and 1928. Serial No. 266,513.

at the same time universality of installation is secured by the provision of a special elbow at 10 which has a very broad and unusually deep bell shaped top 11 into which is loosely fitted the reduced neck portion 12 of the basin NT oFFIcs. v

5. Obviously the elbow may be turned to any angle whatsoever with reference to the basin about the discharge neck12 as an axis and.

the drain may thus lead in any direction from the point of installation. The elbow 10 may v be loosely fitted into a standard drain'tile 15,

' as illustrated, the drain tile being provided r with a proper pitch toward the storm sewer. g

10.and the. collecting basin 5 permits The loose connection between the elbow fitting these parts to retain engagement for the l operative discharge of water irrespective of relative vertical movement. In other words frost acting to heave the groundupwardly against flange 6 of. the basin may elevate the basin considerably, above its normal position in elbow 10 butthe length of flange 11 and neck 12 is such that'an operative communication and registry of the parts willnevertheless be maintained- It iseven possible for elbow 10 to be heaved by frost without losing its operative engagement either with the basin or the tile. Contrary to the usual practice,'. no cement is used in these joints, the length of the joint and its loose fit being depended upon .to'permit relative movement while, maintain ing engagement.
